Kell Brook and Gennady Golovkin go toe-to-toe at Londons O2 Arena on Saturday night with both men putting their unbeaten record on the line.?In the video above, ESPN boxing correspondent Steve Bunce discusses his four favourite bouts from history between two previously undefeated fighters. But which was the best fight? Vote below...Muhammad Ali vs. Joe FrazierDate: March 8, 1971 Venue: Madison Square Garden, New York Pre-fight record: 31-0 (25 KO) vs. 26-0 (23 KO)Dubbed the Fight of the Century, Frazier downed Ali in 15 rounds to retain his WBC and WBA world heavyweight titles. Ali exacted his revenge two years later, winning in 12 at the same venue. He beat Frazier again in 1975 in the so-called Thrilla in Manila.Floyd Mayweather vs. Saul AlvarezDate: Sept. 14, 2013 Venue: MGM Grand, Las Vegas Pre-fight record: 44-0 (26 KO) vs. 42-0 (30 KO)In the richest fight of all time, Mayweather won with all scorecards in his favour except one. Mayweather ended his career a year and four fights later and, crucially, still undefeated. The defeat remains Alvarezs only reverse and he takes on Britains Liam Smith in Texas on Sept. 17 for the WBO light middleweight title.Mike Tyson vs. Michael SpinksDate: June 27, 1988 Venue: Convention Hall, Atlantic City Pre-fight record: 34-0 (30 KO) vs. 31-0 (21 KO)Not one for the Spinks family scrapbook as Tyson knocked him out in just 91 seconds to become the lineal champion. It proved to be Spinks last fight. Tysons first defeat came two years later against Buster Douglas. He went on to lose five more bouts in a career spanning 20 years.Carlos Zarate vs. Alfonso ZamoraDate: April 23, 1977 Venue: Inglewood Forum, Los Angeles Pre-fight record: 38-0 (37 KO) vs. 29-0 (29 KO)A showdown between two of Mexicos biggest names was inevitable and, in 1977, the so-called Battle of the Z Boys was won in the fourth round by Zarate. The defeat knocked Zamoras career off the rails, and he went on to lose four of his remaining eight fights before calling it a day. Zarates first loss came a year later, and his career ended in 1988 with a record of 66 wins and four defeats. Hyun-Jin Ryu Jersey .J.
